"Photo" is misleading because a photo is made by photons, but only electrons are small enough to show the structure of a virus. With electrons, they can get slices of the virus like this: https://pic8.co/sh/5fgHiP.jpg
With many slices of the same object, they can reconstruct the 3D structore of the object. And because electrons have no color, they add some for effect. So, after all, it's not just one of the many models or artist renderings of the virus, but it is not a photograph either.
